Fortress

Fortress burst onto the scene in 2009's Invincible #67, a Modern Age creation from Cory Walker that planted its flag squarely in Image Comics' sprawling, interconnected universe. With appearances spanning Invincible, ShadowHawk, and the ambitious crossover event Image United, this character moves in genuinely impressive company — sharing pages with the likes of Dragon, ShadowHawk, and Sara Pezzini, the heavy hitters of Image's roster. It's a compact but meaningful footprint, the kind that marks a character worth tracking down for any serious Image collector with an eye for the connective tissue that makes a shared universe feel alive.
